Legendary cellist Yo-Yo Ma threw an impromptu concert at a vaccination clinic in Massachusetts over the weekend after the 65-year-old musician received his second dose of the coronavirus vaccine.

According to The New York Times, Ma had to be under observation for 15 minutes after receiving his shot on Saturday at the Berkshire Community Colleges vaccination site in Pittsfield.

Ma, who has a residence in Berkshire, used the brief window to perform Ave Maria and more songs as others waited in observation.

In footage posted by the college on Facebook, the cellist can be seen performing in jeans, a t-shirt, and jacket with a black cap.

Richard Hall, who works with the Berkshire COVID-19 Vaccine Collaborative, told The Berkshire Eagle that Ma had wanted to give something back” and called the impromptu performance very special. 

What a way to end the clinic, Hall told the outlet.

State Rep. William Smitty Pignatelli (D), who represents the Berkshire District, also praised Ma for the surprise performance, saying on Twitter the renowned cellist “is always a classy act.
